What size vanity sidesplash do I need for my bathroom?

Measure the width of your vanity and the height from the countertop to where you want the splash to end—most standard sidesplashes are 4-6 inches tall and come in widths matching common vanities (24, 30, 36, 48 inches). Check your vanity's exact dimensions before ordering to avoid gaps or overhang.

What's the difference between ceramic tile and cultured marble sidesplashes?

Ceramic tile is more durable and easier to replace individual pieces if damaged, while cultured marble offers a seamless, high-end look with fewer grout lines to maintain. Tile is better for high-moisture areas, but cultured marble is simpler to clean and install.

Do I need a backsplash if I'm installing sidesplashes?

No—sidesplashes protect the walls on either side of the vanity and are a separate feature from a backsplash, which runs behind the sink. Many people install both for complete protection, but sidesplashes alone are sufficient if your vanity is against a non-water-exposed wall.

Should I buy pre-made sidesplashes or have them custom-made?

Pre-made options are faster and cheaper, working well if your vanity has standard dimensions, while custom sidesplashes suit unusual layouts or specific design preferences. Go custom only if your space has odd angles or you need a specific material or color not available off-the-shelf.

What material is easiest to maintain in a humid bathroom?

Ceramic tile and porcelain are the most practical for humidity since they resist moisture absorption and are simple to wipe down. Cultured marble and laminate can work too, but avoid wood-based materials as they'll warp or swell over time in high moisture.
